Herringbone (cloth)

Herringbone, also called broken twill weave, describes a distinctive V-shaped weaving pattern usually found in twill fabric. It is distinguished from a plain chevron by the break at reversal, which makes it resemble a broken zigzag. The pattern is called herringbone because it resembles the skeleton of a herring fish. Herringbone-patterned fabric is usually wool, and is one of the most popular cloths used for suits and outerwear. Tweed cloth is often woven with a herringbone pattern.

Fatigue uniforms made from cotton in this weave were used by several militaries during and after World War II; in US use, they were often called HBTs.
